Low voltage pyrotechnic igniter assembly

Abstract

The electric pyrotechnic igniter of the present invention comprises a controlled power source providing low-voltage electricity to one or more remotely located, replaceable ignition elements which are housed in compression clips capable of holding the ignition elements into direct contact with firework fuses.

1. A igniter assembly, comprising: a low voltage power supply with mechanism and housing; for same, associated control compression clip with electrical connectors and seat for an ignition element, and a heat producing ignition element. 
   
   
     2. The igniter assembly as claimed in  claim 1 , wherein the ignition element is composed of an area of resistive heating material as the heating member, a structural substrate of non-conductive, non-flammable material as a base for said heating member, and a means of attaching said heating member to said substrate. 
   
   
     3. The igniter assembly as claimed in  claim 2 , wherein the heating member is securely attached or mounted to the structural substrate of the ignition element by a member of a group consisting of conductive tape, adhesive, staple, rivet or by the configuration of the heating member itself. 
   
   
     4. The igniter assembly as claimed in  claim 2 , wherein the heating member of the ignition element is a configuration of wire, ribbon, film or membrane resistive heating material, having sufficient area and configuration to produce a concentrated area of heat sufficient enough to ignite pyrotechnic fuse material. 
   
   
     5. The igniter assembly as claimed in  claim 2 , wherein the ignition element is constructed to mate with the conductive seat, such that the heating member is in electrical contact with both positive and negative contact points in said seat and produce a completed electric circuit with the power supply and the switching device.
